Description

  The present invention relates to an apparatus for removing a vine plant that automatically and appropriately cuts off the tip of a vine plant such as kuzu that rolls up along a branch line or the like that supports a utility pole, thereby effectively inhibiting growth.

In order to support the utility poles, vines such as kudzu are easily rolled up and entangled with metal branch lines installed obliquely downward from the appropriate upper part of the utility pole toward the ground. When the vines that have grown from the ground reach the electric wires and live parts from the utility poles, they may cause short circuits and ground faults, which are likely to hinder the stable supply of power. Further, if a vine plant entangled with a branch line is left unattended, the branch line is likely to corrode over time due to moisture such as rainwater retained by the vine.
For this reason, although the work which removes a vine is appropriately performed conventionally, the vine which reached the height of several meters-10m by work from the ground is removed completely over the full length. Was not easy. Although it is effective to remove it before reaching the high place, vine plants grow about 1 m per day in the summer, so even if the frequency of patrol is increased, it is necessary to reach the high place on all branch lines. It is difficult to stop completely. In addition, increasing the frequency of patrols for removing vines has limitations due to personnel costs and personnel deployment.

Patent Document 1 (Japanese Patent Laid-Open No. 08-205368) and Patent Document 2 (Japanese Patent Laid-Open No. 11-30056) describe a vine plant that grows upward while tangling to a branch line from the ground by being attached to an appropriate position of a branch line of a utility pole. An apparatus for preventing the roll-up of the paper is disclosed.
However, the wrapping prevention device of Patent Document 1 is not only inconvenient to transport due to its excessive size, but also does not inhibit the growth of the vine plant itself. It is impossible to prevent it from growing up and reaching the electric wire.
Patent Document 2 focuses on strength and convenience during transportation and cannot effectively prevent upward growth via the outer surface of the prevention device.

In Patent Document 3 (Japanese Patent Application Laid-Open No. 2007-325420), a case portion is disposed at an appropriate position of a branch line of a utility pole so as to be rotatable around the branch line, and a blade is provided in a lower opening of the case portion. When the case is rotated by wind power, the vine plant that has entered the lower opening of the case portion is cut by the rotating blade.
However, while it cannot be cut unless it rotates, cutting using the natural force of wind power lacks certainty and is inefficient.

Patent Document 3 discloses a configuration in which a vine is cut with a blade by rotating the case portion with a motor driven by electric power from a solar cell arranged in the case portion.
However, in this configuration, since the power from the solar cell is always output to the motor without being controlled and the motor is continuously driven as long as there is power, the motor is driven even when no vines are present in the case part. As a result, power is wasted and the durability of the solar cell and motor may be reduced. In addition, the tip of the vine plant that has climbed upward along the branch line does not necessarily surely enter the case part where the blades are arranged, and is likely to extend along the outer surface of the case part. In other words, since the method of guiding the vines into the case was left to nature, the certainty was poor.

  In addition, the malfunction which a vine plant gives to an electrical installation is not restricted to a utility pole branch line, but brings the same malfunction to wires, such as an electric wire, a columnar thing, a rod-shaped thing, etc.

Japanese Patent Laid-Open No. 08-205368 Japanese Patent Laid-Open No. 11-30056 JP 2007-325420 A

As described above, the vines that grow along the electrical facilities of the utility poles need to be removed at the early stage of growth, which is the stage before reaching a high place that is not reachable by humans. It is impossible to reliably carry out the removal operation at the initial stage of growth for all the branch lines.
The present invention has been made in view of the above, and can reliably guide the tip of a vine plant into a device installed at the lower part of a branch line, and can detect that a vine plant has entered the device. The purpose of the present invention is to provide a vine plant removal device that can carry out removal and growth prevention work at an early stage of growth while saving power by increasing the durability of moving parts by performing cutting work. Yes.

  In order to achieve the above object, a vine plant removing apparatus according to the present invention is a vine plant removing apparatus for cutting a vine plant wound around a vertically extending protection object, wherein the protection object Mounted in a state of covering a part, the upper part is closed, the lower part is opened, and at least a part is translucent and rotates around the part to be protected located in the protective cover A freely configured rotating body, a rotating blade that rotates together with the rotating body, a motor that rotationally drives the rotating body, a photosensor that detects a vine plant that has entered from the lower opening of the protective cover, A solar battery that is disposed inside the protective cover and generates power by receiving light from the light-transmitting region, a storage battery that stores electric power generated by the solar battery and supplies the electric power to the motor, and detection from the photosensor Signal And control means for controlling the timing of outputting the power from the battery to the motor Zui, characterized by comprising a.

  According to the present invention, the tip of the vine plant can be reliably guided into the device installed at the lower part of the branch line, and the cutting operation is performed after detecting that the vine plant has entered the device. Removal and growth prevention work can be performed at an early growth stage while saving electric power and increasing the durability of the movable part.

It is explanatory drawing which shows the installation state of the removal apparatus of the vine plant which concerns on one Embodiment of this invention. (A) And (b) is the longitudinal cross-sectional view which shows the internal structure of the removal apparatus of a vine plant, and a bottom view.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is an explanatory view showing an installed state of a vine plant removing apparatus according to an embodiment of the present invention, and FIGS. 2 (a) and 2 (b) are longitudinal sections showing an internal configuration of the vine plant removing apparatus. It is a figure and a bottom view.

The vine plant removing apparatus 1 (hereinafter referred to as the removing apparatus 1) of the present invention is spirally wound around the outer periphery of a long protection object (for example, a utility pole branch line) 100 extending in the vertical direction and grows upward. It is a means for guiding the tip of the vine plant 110 coming and other parts into the apparatus and cutting it.
The removal device 1 is attached to a lower part of the utility pole branch line in a state of covering a part of the utility pole branch line 100, the upper part is closed, the lower part is opened, and at least a part of the protective cover 2 having translucency, A rotating body 20 configured to be rotatable around a predetermined portion of the utility pole branch line 100 located in the protective cover, a rotary blade 25 that rotates together with the rotating body, a motor 40 that rotationally drives the rotating body, and the protective cover 2 A photosensor 45 that detects the vine plant 110 that has entered from the lower opening, a solar cell (solar panel) 50 that generates power by receiving light from the light-transmitting portion (light-transmitting region) 3 of the protective cover, A storage battery (secondary battery) 55 capable of accumulating the electric power generated by the solar battery and supplying it to a motor and a photosensor (or a battery), and a power supply from the storage battery based on a detection signal from the photosensor. A control unit (not shown) and outputs to the motor includes (CPU, memory, etc.) and, the.

The protective cover 2 according to the present example has a translucent region 3 above the intermediate portion M at a substantially intermediate position in the longitudinal direction and a light-shielding region 5 below the intermediate portion M, and the branch line L along the axial direction. It is divided into two. By splitting it in half, it becomes easy to attach to the utility pole branch line. As shown in FIG. 2 (b), each split piece 7 can be freely opened and closed by using one connecting edge of each split piece 7 as a hinge portion 8 as shown in FIG. Fixing is performed by fixing means 9 (bolts and nuts in this example). Further, it is preferable that the other connection end edge is sealed in a watertight manner with an adhesive tape or the like.
The protective cover 2 is mainly composed of a highly insulating resin material.
The protective cover 2 prevents extraneous light from entering the interior by the light shielding region 5 positioned below, while the translucent region 3 positioned above introduces the extraneous light into the interior. For this reason, the vine plant which has risen along the utility pole branch line rises toward the light introduced from the translucent region 3, and easily enters the inside from the lower open portion of the protective cover. In particular, by forming the light-transmitting region 3 in a tapered shape as shown in the figure, incident light from the tapered surface travels as a strong light amount downward to the protective cover and has a property of extending toward strong light. Sexual plants will be actively guided into the protective cover 2. Further, by constructing the entire light-transmitting region 3 or partially in the shape of a convex lens, it is possible to increase the light condensing power and make it easier for the vines to enter from the lower opening to the inside of the protective cover.
In addition, said structure is only an example and it is good also considering the whole protective cover as a translucent area | region. By setting the entire protective cover as a light-transmitting area without providing a light-shielding area, it is possible to reliably guide the vine plant rising along the utility pole branch line into the protective cover.

The rotating body 20 (the split structure) including the rotary blade 25, the motor 40, and the storage battery 55 are unitized, and are fixed to a predetermined part of the utility pole branch line 100 before the protective cover is attached.
The rotating body 20 is rotatably supported by a cylindrical fixing member (split structure) 10 that is fixed in close contact with the outer surface of the utility pole branch line, and the motor output gear 40a is engaged with the internal teeth of the annular gear 22 to engage the motor. It receives the driving force from and rotates. The rotating body 20 includes a cylindrical portion 21 having an annular gear 22, and includes a configuration in which the cylindrical portion 21 is rotatably disposed in a space between the fixed member outer wall 11 and the fixed member inner wall 12. In other words, the outer peripheral surface of the rotating body 20 is surrounded by the fixing member outer wall 11 having an annular opening 11a for projecting the rotary blade 25, and the fixing member inner wall 12 is disposed opposite to the inner peripheral surface of the rotating body. ing. A bearing member 15 such as a rolling bearing or a low friction member is disposed between the outer peripheral surface of the rotating body and the outer wall 11 of the fixing member and between the inner peripheral surface of the rotating body and the inner wall 12 of the fixing member. The rotating body is configured to rotate stably.
The fixing member 10 is configured such that the fixing member outer wall 11 can be attached to and detached from the fixing member inner wall 12, so that a rotating body can be incorporated in the space between the two members.
Thus, the rotating body 20 includes a cylindrical portion 21 that is rotatably supported in a cylindrical space between the outer wall of the fixing member and the inner wall of the fixing member, and an annular gear 22 provided at the end of the cylindrical portion. And is dimensioned so that the annular gear meshes with the output gear of the motor. The rotating body is also divided into two parts. By splitting into two, the fixing member can be assembled by retrofitting. The divided pieces divided into two are assembled by an adhesive or other fixing means.

The rotating blade 25 is preferably made of metal in order to exhibit and maintain a sufficient cutting ability, but the other part of the rotating body may be made of a durable resin material. The tip of the rotary blade extends to the nearest position of the inner wall of the protective cover, or extends into the recess provided in the inner wall of the protective cover as shown in the figure, so that the vine plant is not cut into the rotary blade. Can be prevented from extending upward. It is preferable that a plurality of rotary blades be arranged on the outer peripheral surface of the rotating body at a predetermined circumferential pitch.
In order to stabilize the rotation of the rotating body 20, a plurality of driven gears 43 that do not have a drive source may be arranged in the fixed member (outer periphery of the utility pole branch line) and meshed with the annular gear 22.

The fixing member 10 and the rotating body 20 are divided into two parts in the axial direction, and are closed after being attached to the outer surface of the utility pole branch line with each divided piece open, and are fixed by a fixture, an adhesive, or the like. The It is preferable to provide a convex portion and a concave portion that are fitted to each other at the joining edge of each divided piece so as to determine the positional relationship.
The fixing member 10 is made of an insulating resin, and when fixing the fixing member to the utility pole branch line 100, the small-diameter cylindrical center member 16 is adhered and fixed to the outer surface of the utility pole branch line, and then fixed to the outer peripheral surface of the center member 16 The member 10 is fixed. The central member 16 also has a split structure in the axial direction, and is fixed after covering the two split pieces on the utility pole branch line.
The fixing member 10 accommodates circuit components such as a motor 40, a storage battery (rechargeable battery) 55, and control means (CPU or the like) (not shown) in the interior thereof. In this example, a motor, a storage battery, Circuit parts are fixed. The motor output gear 40a is assembled so as to mesh with the internal teeth of the annular gear 22 of the rotating member. The output gear and the internal teeth may be spur teeth, a helical gear, or a bevel gear.

  A solar cell 50 is disposed at an appropriate position in the protective cover, in this example, on the inner surface of the light transmitting region 3 of the protective cover. The arrangement area of the solar cell 50 is set to be as narrow as possible so that sunlight entering the inside of the protective cover from the light transmitting region is not significantly blocked. The solar cell 50 may be disposed on the utility pole branch line or on the fixing member 10. The solar battery and the storage battery are connected by an electric wire (not shown), and the electric power generated by the solar battery is stored in the storage battery. When the solar cell is fixed to the light-transmitting region, the area and arrangement are taken into consideration so as not to disturb the incident light. The solar cell 50 may be disposed on the outer surface of the fixing member 10 or any other part.

A spacer 60 made of an elastic member such as a coil spring or a leaf spring is disposed between the inner surface of the protective cover 2 and the outer surface of the fixing member 10 to prevent the posture of the protective cover 2 from being displaced with respect to the fixing member (electric pole branch line). By making the spacer 60 an elastic member such as a coil spring instead of a rigid member, it is possible to prevent the protective cover from being damaged even when a vibration shock is applied.
Between the outer wall 11 of the fixing member and the inner wall of the protective cover, a photo sensor 45 such as a photo interrupter or a reflective photo sensor is arranged so that a part of the vine plant, particularly the tip, has entered the protective cover. Configure to detect. The photo sensor 45 is placed on the upper side of the rotary blade, and the control means starts driving the motor when the vines (tips of shoots, other parts) pass through the rotary blade and are detected by the photo sensor. Rotate the rotary blade. The control means may stop the motor immediately when the photo sensor is no longer detected, or may stop the motor after continuously driving the motor for a predetermined time after it is no longer detected.

By arranging a plurality of photosensors at a predetermined pitch in the circumferential direction inside the protective cover, it is possible to detect without leakage.
It is preferable that the motor is configured to be capable of forward and reverse rotation, and the cutting of the vine is ensured by switching the rotation direction of the rotating body. In this case, the rotary blade has a double-edged structure.
Although a photo sensor may be arranged below the rotary blade, the motor rotates as long as the lower photo sensor continues to detect the uncut portion even if the rotary blade cuts the tip of the vine. Since it will continue, power loss may occur.

The photosensor is preferably operated with electric power from a battery (not shown) disposed in the fixed member, but electric power from a storage battery may be used.
The electric power stored in the storage battery 55 is supplied to the motor 40 at the timing when the photo sensor 45 detects the invasion of the vine by the control from the control means, and the supply of electric power is stopped after the rotary blade cuts the vine. Therefore, power can be saved.
Since the photosensor can detect vines regardless of daytime or nighttime, the rotating blade can be operated to prevent the growth of the vines every time the entry of the vines is detected regardless of the time zone.

Moreover, you may make it rotate a rotary blade by driving a motor regularly regardless of the presence or absence of the detection of a vine by a photo sensor by control from a control means. Since the light-emitting element and the light-receiving element that constitute the photosensor may be malfunctioning due to contamination over time, periodic cutting work is effective in the growing period such as summer.
Moreover, since the protective cover 2 can be removed from the utility pole branch line separately from the fixing member (rotating body) fixed to the utility pole branch line side, only the protective cover is removed and the rotary body, motor, storage battery, photosensor, solar battery, etc. Maintenance such as inspection, repair, and cleaning becomes easy. Further, the protective cover 2 can be divided into the light shielding area 5 and the light transmitting area 6 from the intermediate portion M, and the interior can be maintained by removing only the light transmitting area 6 in a state where the removing device 1 is installed on the utility pole branch line. You may comprise. In particular, since it is assumed that the cutting site of the vine plant 110 remains and accumulates as small pieces 110a inside the protective cover, in the present invention, the protective cover is disassembled and maintenance after removal is easily configured. Yes.
In other words, after cutting the tip of the vine plant, by continuing to rotate the rotary blade, the cut tip portion is repeatedly cut by the rotary blade in the process of falling, and further broken into pieces, and falls downward beyond the rotary blade. It becomes easy. Therefore, it becomes difficult for the cut part to remain in the protective case including the upper part of the rotary blade. However, since fine debris pieces adhere and remain in the protective cover over time, regular maintenance is necessary.

<Summary of Configuration, Action, and Effect of the Present Invention>
1st this invention is the removal apparatus 1 of the vine plant which cut | disconnects the vine plant 110 wound around the protection target object 100 extended to an up-down direction, Comprising: It mounts | wears in the state which covered a part of protection target object, A protective cover 2 having an upper portion closed, a lower portion opened, and at least a portion having translucency; a rotating body 20 configured to be rotatable around a portion to be protected located in the protective cover; A rotary blade 25 that rotates together with the rotating body, a motor 40 that rotates the rotating body, a photosensor 45 that detects vines that have entered from the lower opening of the protective cover, and a transparent sensor disposed inside the protective cover. The solar cell 50 that generates power by receiving light from the light region 3, the storage battery 55 that stores the electric power generated by the solar cell, supplies the electric power to the motor, and the electric power from the storage battery based on the detection signal from the photosensor motor Characterized by comprising a control means for controlling the output timing.

The vines such as kuzu have the property of wrapping around thin utility poles and growing upward. On the other hand, since the sprout has the property of extending toward strong light, the vine plant that has risen along the power pole extends toward the incident light from the translucent area provided in the protective cover, and enters the protective cover. I will enter. Since the fixing member 10 is arranged in the center of the protective cover, the vine plant that has grown upward rises along the outer surface of the fixing member and passes through the space between the fixing member and the protective cover. Will rise further. In this space, a plurality of rotary blades 25 are positioned at a predetermined pitch in the circumferential direction, but when a vine plant passes through the space between the rotary blades and further rises, it is detected by the photosensor 45. When the photo sensor transmits a signal indicating the invasion of vines to the control means, the control means supplies the electric power stored in the storage battery 55 to the motor 40 to start the rotation of the rotating body and the rotary blade.
The storage battery 55 stores the electric power generated by the solar battery 50 by sunlight during the day, and the control means rotates the rotary blade at an appropriate timing and an appropriate time triggered by detection by the photosensor. In addition, the rotary blade can be rotated for a predetermined time periodically or irregularly irrespective of detection by the photosensor.
The part of the vine plant cut by the rotating blade becomes a small piece and falls from the open part below the protective cover.
Maintenance such as internal cleaning and inspection is facilitated by disassembling and assembling the protective cover.

The apparatus for removing a vine plant according to the second aspect of the present invention is characterized in that the protective cover has a light shielding region 5 below the intermediate portion in the vertical direction and a light transmitting region 3 above the intermediate portion. .
By setting the light shielding area below the protective cover and the light transmitting area on the top, it is possible to increase the amount of light incident on the inside of the protective cover, especially the top, leading to vines in the protective cover. It becomes easy.
